To all whom it 'may concern.'

Bc it known that l, -JoUN W. Finns,- a citizen ofthe United States, and a resident of VVinst'on Salem, county of Forsyth, State lmprovement in Humidifiers, of which the fol lowing is a specification.-l

- My invent-ion reference tohumidifiers and consists/of certain improvements 10 which are fully set forth in the following .speciiication and shown in the accompanying drawings which. form a part thereof.

My invention-more particularly relates to means for automatically'controlling the supply of Water to the humidifying apparatus under the control of the condition of the 'atmosphere of: the room or` compartment in which the apparatus is located, whereby the humidity imparted to the atmosphere of the room may be maintained in a substantially constant condition.

My improvements are valso designed to permit a greater or less humidity to be provided under automatic regulation, as may be required to suit the conditions prevailing i Within the room or compartment in which the apparatus is located.

lMy invention, while being adapted to humidifiers of various constructions, is more particularly designed foruse in connection ith humidiers of the character disclosed in Letters Patent No, 847,300' and granted to me on J an'.25, 1910, and iii ivhich a regulated stream of Waterl is projected upon a rapidly revolving disk, from the perimeter of which it is thrown as a yfilm and caused 'to be impacted by a circular row/of abut-- ments ,by means of vvhich it is sub-divided into'a vapor, the density of which is dependent upon the amount of Water delivered to the revolving disk in-a given time.

' My invention consists,l in its application to the aforesaid humidifying'apparatus, Aof a nozzle for supplying-water to the revolving disk, means` for 'delivering a stream of Waterfto the' nozzle, and means controlled by the humidity of. the atmosphere' todi vert-the stream ofv Water from the nozzle whenever the humidity ofthe atmosphere exceeds a predetermined degree.

More specifically, my invention consists of zertainl details of construction which are .'j illustrated in the `drawings and more fully described-hereiriafter. generally, comprehends the My invention d features in addition with those hereinafter describedI and all of which Aare more particularly defined in the claims. y vReferring to the drawings, Figure 1 is a side elevation of my improved humidifying apparatus with "rear elevation o and bracket removed; Fig. 3 is a cross sectional view on line :1iof Fig. 2; Fig. 4 is a plan view looking down upon the im mediate 'means for controllin the stream of water; Fig. 5 is a sectiona the sametaken on line z-z of Fig. 4; Fig. 6 is a perspective view illustrating the construction of the abutments by which the film ofwater is sprayed; and Fig. 7 is a cross section of the diverting means.

The lower artof' the well, immediately bielow the outliet of nozzle v19 is provided with an elongated tubular part 20 adapted to receive' the water'froin the nozzle when not otherwise prevented. i The 'water received in the tubular v art 20 H OWS downward intothe nozzle 15 w ich delivers the water upon the back of the revolving' disk 5.- `This water,

of water fromthefnozzle 19 should'the valve 18 be turned open too muchfso-as .to prefvent' the excess of water passing down to the disk. 4An water passing fromwthenozzle 19 which ces not find its way into the tubuv lar part 20, isgeceivcd'in the well and drains of bythe pipe 21, from which it'is dis# charged into 'the' basin 11 and thence through the head 8 intothe waste pipe 10.

' When the roper hygrometric condition of the atmosp ere is had, `the parts' will be in the condition indicated' in Fi 2; andl under these conditions, allof t e water which is intended to be used is permitted to "pass from thev nozzle 19 into the tubular part 20 and thence bythe nozzle 415 to the revolving disk 5. B the adjustment of the hand valve 18 slip tly more water may pass from the nozz e lum-idcrease above the redetermin amount the `Wooden portion 2 of the arm 25 expands to' agi-eater degree than the metal part 26, with the result-that thebar 22 is shifted sov that the diverting head 23 is brought into 'contact with the small stream of water the nozzle 19 and causes it to be diverted to one side of the `.tubular part 20 'whereby the supply of water to the disk is'temporarily cut 'oil' n 19 than is actuflly ree' quired formaintaining the degree of ity required. If thejhumidit should in# and this condition maintained until the de- 'l grec of humidity is reduced tothe predetermined ainount and sli htly below theI same. Vhen this condition is reached;A thc curved aul arm`25 will tend to increase its curvaturel and will 4move the bar 22 inthe QPPOSte direction, so "that vthe divertir'ig head '23 thereof is moved o ut of colitact'witli the stream of water issuingfrom the4 nozzle 19 and said water will again flow into the tubular art 20 and lthence Idown through the nozz e15 to the revolving disk 5.V

It will be understood, hat the device will operate automatically to control the amount vapor. without, as a matter of act,'ei ther 4changingthe speed ofthe machine or of the amount of water. which is' passing .through the nozzle 19, Theadiustment oftheI stream of water from thenozzle 19Vdoes not have e to' be 'very accurately made because the autolmaticdevices, control the amount of water ldissipated into vapor'to, maintain the hymetric conditions justwhat is desired.

t is ev'ident, however, that itis not desirable that too-largev astream of water shall 'pa through the :noz le 15, as that would iio f produce a'vapor ten ing to form a 'spi-ay .which wouldV be objectionable; and consequently, the valve 18'slioul'dbei of a form which will allow of. adjustment] for-- L slight differences in quantity'bf wateripermitted to pass, so that apppoximately the right amount 'of water mayfbc supplled to the machine. As beoreystated, any careless handling ofl tlievalve 18 will causethe jet tubular pxart4 2 0= and Aescape by the Waste Iip'e 21 wi out assin to the revolving isl, This free ow 0 water may be resorted to' occasionally when 'it' is desired to.
